I am having problems using an UPDATE command in my asp.net project. The project allows a user to log in via a login page which matches the username and password to a record in the database and saves the username as a cookie. I then have a settings page which I want to allow a user to edit their account details but when I use the UPDATE function the query is executed without any errors but the update doesn't occur. I am using an AccessDataSource and an UpdateCommand hopefully someone can find a problem with my code and steer my in the correct direction. Thanks in advance
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim sqlcmd As String
sqlcmd = "SELECT FirstName, SecondName, UserName, DOB, Password FROM UserTable WHERE UserName = '" & Request.Cookies("UserInfo")("userName") & "'"
AccessDataSource1.SelectCommand = sqlcmd
If (Not Page.IsPostBack) Then
Dim sqlcmd2 As String
sqlcmd2 = "UPDATE [UserTable] SET [FirstName] = ?, [SecondName] = ?, [UserName] = ?, [DOB] = ?, [Password] = ? WHERE [UserID] = ? AND ISNULL (([FirstName] = ?) OR ([FirstName] IS NULL AND ? IS NULL)) AND (([SecondName] = ?) OR ([SecondName] IS NULL AND ? IS NULL)) AND (([UserName] = ?) OR ([UserName] IS NULL AND ? IS NULL)) AND (([DOB] = ?) OR ([DOB] IS NULL AND ? IS NULL)) AND (([Password] = ?) OR ([Password] IS NULL AND ? IS NULL))"
AccessDataSource1.UpdateCommand = sqlcmd2
End If
End Sub

Sorry if it is all a bit messy but this is my first post and I'm not entirely sure what I'm doing.
